feat(agent): 统一文件读取+联网检索+只读库查询+generic strict沙箱(对齐Hermes信息摄入能力)
- 新增 file_read.py: v1/v2 共用统一读取(分页续读+docx/pdf解析+显式截断告知) 根治立项书76088字符只读到30000(v2)/12000硬截无提示(v1)的真实翻车 - 新增 web_tools.py: web_search(Bing RSS优先+HTML兜底)/fetch_url(超长落盘webcache+read_file续读) SSRF三层防护(公网域名/DNS私址拒绝/重定向逐跳)+不可信数据标注; 修复 aiohttp content.read(n) 对 chunked 响应提前返回半截的坑(改 resp.read()) - 新增 db_query.py: query_project_data 只读白名单查询(强制project_id参数化+where/order_by注入校验+审计) - agent_loop.py(v1角色agent): read_file 12000硬截→共享file_read分页; AGENT_TOOLS 加三工具(补required防全参必填); _run_shell 加 strict 档(通用会话:不挂平台目录+可写根收窄到用户专属目录); PM/QC/RETRO prompt 工具清单同步 - agent_loop_v2.py(v2会话agent): _t_read_file 改走共享模块; 新增三工具 handler; generic run_command 强制strict+无bwrap拒绝
